Ubuntu – Dell Inspiron 7347 – Inactive cursor with the touchpad on UBUNTU 14.04

touchpad

After installing Ubuntu 14.04, my touchpad became inactive. Everything works fine on Windows 8, but in Ubuntu it does not respond.

I have tried the following command, but the problem persists :(.

synclient touchpadOff=0

sudo apt-get update

— (this works fine)

sudo apt-get install wget gdebi wget http://http.us.debian.org/debian/pool/main/s/synaptiks/kde-config-touchpad_0.8.1-2_all.deb

— ((this does not work- could not find package by regex…))

Any help is appreciated.

Thanks for the useful help. Problem solved! 🙂

You can fix it this way:

sudo -H gedit /etc/default/grub

In the open window edit line

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

it should look this way

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i8042.nopnp"

Save file and run

sudo update-grub

Run

echo "blacklist i2c_hid" | sudo tee /etc/modprobe.d/i2c-hid.conf
sudo depmod -a
sudo update-initramfs -u
echo "synaptics_i2c" | sudo tee -a /etc/modules

Reboot.

Please be careful, do not retype these commands, but copy them and paste into the terminal, or you can break the whole system, if mistype.

This solution disables Plug & Play for i8042 devices, then disables i2c-hid module and enables synaptics_i2c instead or it.

Plug & Play triggers a wrong module for this device.

Ubuntu – Help trying to get two-finger scrolling to work on Asus UL80VT

To get your synclient settings to stick you can add them to xorg.conf. I did this recently for my macbook pro in 12.10 and it works pretty well.

You can also specify a separate configuration file in /etc/X11/xorg.conf.d/ file to keep things neater. Here's a step by step:

Create /etc/X11/xorg.conf.d (if it doesn't already exist)

sudo mkdir /etc/X11/xorg.conf.d
Create and edit /etc/X11/xorg.conf.d/10-synaptics.conf

gksudo gedit /etc/X11/xorg.conf.d/10-synaptics.conf

Make it look like the following:

#Sample /etc/X11/xorg.conf.d/10-synaptics.conf
Section "InputClass"
  Identifier "touchpad catchall"
  Driver "synaptics"
  MatchDevicePath "/dev/input/event*"
  MatchIsTouchpad "true"
  Option  "SHMConfig"           "true"
  Option  "TapButton1"          "1"
  Option  "TapButton2"          "2"
  Option  "TapButton3"          "3"
EndSection

Save and logout/login again. If the xserver fails to load and you get forced into low graphics mode then edit the file again and comment everything out, or mv /etc/X11/xorg.conf.d/10-synaptics.conf ~/10-synaptics.conf.backup and reload again to get back to normal.

For posterity, my current setup for my macbook pro 2012 13" is as follows (warning, I like my touchpad rather sensitive). Try any of these options using synclient before putting them into xorg.conf!

Section "InputClass"
      Identifier "touchpad catchall"
      Driver "synaptics"
      MatchIsTouchpad "on"
      MatchDevicePath "/dev/input/event*"
      MatchProduct "bcm5974"
      MatchIsTouchpad "true"
      Option  "SHMConfig"           "true"
      Option  "FastTaps"            "1"
      Option  "MaxDoubleTapTime"    "100"
      Option  "BottomEdge"          "6000"
      Option  "FingerLow"           "60"
      Option  "FingerHigh"          "90"
      Option         "ClickFinger3" "2"
#      Option         "FingerLow"             "30"
#      Option         "FingerHigh"            "80"

      Option         "HorizTwoFingerScroll" "1"
      Option         "VertScrollDelta" "100"
      Option         "HorizScrollDelta" "100"
      Option         "MultiFingerButton" "2"
      #Option         "TapButton1" "1"
      Option         "TapButton2" "3"
      Option         "TapButton3" "2"
      Option         "MinSpeed" "1"
      Option         "MaxSpeed" "2"
      Option         "AccelFactor" "0.01"
#      Option         "AreaBottomEdge" "5000"

Ubuntu – How to config Trackpoint + Synaptics touchpad only enable clicks on Linux (Ubuntu)

Well, this is not the direct answer, but a suggestion and examples. If you run xinput, you will get list of your devices. Then run xinput list-props $id where $id is your touchpad id in the list.

You will have a list of options like this:

$ xinput list-props 13
Device 'SynPS/2 Synaptics TouchPad':
    Device Enabled (135):   1
    Coordinate Transformation Matrix (137): 1.000000, 0.000000, 0.000000, 0.000000, 1.000000, 0.000000, 0.000000, 0.000000, 1.000000
    Device Accel Profile (268): 1
    Device Accel Constant Deceleration (269):   2.500000
    Device Accel Adaptive Deceleration (270):   1.000000
    Device Accel Velocity Scaling (271):    12.500000
    Synaptics Edges (292):  1765, 5371, 1637, 4453
    Synaptics Finger (293): 25, 30, 0
    Synaptics Tap Time (294):   180
    Synaptics Tap Move (295):   234
    Synaptics Tap Durations (296):  180, 180, 100
    Synaptics ClickPad (297):   1
    [...]

You can change all of these on-the-fly with xinput set-prop $id $propId $value where $id is the device id, $propId is property id in brackets and $value is what you want it to be. For example:

xinput set-prop 13 135 0 sets Device Enabled (135) to 0 and this will disable the touchpad.

You will need descriptions of properties and a way to make your changes permanent. Descriptions can be found in man synaptics, but wait, they are in another cryptic format! Let's see why.

To make changes permanent, you need to create conf file in /etc/X11/xorg.conf.d, for example 30-tochpad.conf with contents like these:

    Section "InputClass"  # you can read more in `man xorg`
            Identifier "all touchpads"  # just a name for this config
            MatchIsTouchpad "on"  # enables this config for all detected touchpads
            Driver "synaptics"  # enables synaptics-specific options below

            # This will disable the device
            #Option "Ignore" "1"

            # There are options that are generic for input-devices or mouse-like devices, see `man evdev`:
            Option "ButtonMapping" "0 0 0 0 0 0 0"  # i disabled all buttons here, for example

            # Here go options from `man synaptics`
            Option "VertTwoFingerScroll" "1"
            Option "HorizTwoFingerScroll" "1"
            Option "PalmDetect" "1"
            Option "ClickPad" "0"                
            # ...etc...
    EndSection

So, man synaptics describes options for xorg.conf and tells how they correspond to xinput list-props output.

PS. I tried to configure trackpoint on my ThinkPad X220 to have only two-fingers-scroll enabled, without clicks or mouse movement. I failed. Maybe you will manage to do what you want (there was an option to disable everything but clicks, maybe Synaptics Off).
